before, at or after seeding with the treated seed of soybean, corn orcotton.

In the present invention, the seed of soybean, corn or cotton is notlimited as far as it is a variety which is generally cultivated as acrop.

Examples of a plant of such a variety include plants to which resistanceto a PPO-inhibiting compound such as flumioxazin; a4-hydroxyphenylpyruvate dioxygenase-inhibiting compound such asisoxaflutole; an acetolactate synthase (hereinafter abbreviated asALS)-inhibiting compound such as imazethapyr or thifensulfuron methyl; a5-enolpyruvylshikimate-3-phosphate synthase-inhibiting compound such asglyphosate; a glutamine synthase-inhibiting compound such asglufosinate; an auxin-type herbicide such as 2,4-D or dicamba; orbromoxynil has been imparted by a classical breeding method or a geneticengineering technique.

Examples of a crop to which resistance has been imparted by a classicalbreeding method include corn resistant to an imidazolinone typeALS-inhibiting herbicide such as imazethapyr, and this has already beencommercially available under a trade name of Clearfield (registeredtrademark). Examples of such a crop also include STS soybean which isresistant to a sulfonylurea-type ALS-inhibiting herbicide such asthifensulfuron methyl. Similarly, examples of a plant to whichresistance to an acetyl CoA carboxylase-inhibiting compound such astrione oxime-type or aryloxyphenoxypropionic acid-type herbicide hasbeen imparted by a classical breeding method include SR corn.

Examples of a plant to which resistance has been imparted by a geneticengineering technique include corn, soybean and cotton varieties whichare resistant to glyphosate, and they have already been commerciallyavailable under trade names of RoundupReady (registered trade mark),Agrisure (registered trademark) GT, Gly-Tol (registered trademark) andthe like.

There are corn andsoybean varieties under the trade name of Optimum (registered trademark)GAT (registered trade mark), which are resistant to both of glyphosateand an ALS-inhibiting compound. Similarly, there are soybean varietieswhich are resistant to an imidazolinone-type ALS-inhibiting compound bya genetic engineering technique, and they have been developed under thename of Cultivance. Similarly, there is cotton varieties which areresistant to bromoxynil by a genetic engineering technique, and this hasalready been commercially available under the trade name of BXN(registered trademark).

A crop such as a soybean which is resistant to dicamba can be producedby introducing a dicamba degrading enzyme such as dicamba monooxygenaseisolated from Pseudomonas maltophilia into a plant (Behrens at al. 2007Science 316: 1185-1188).

By introducing a gene encoding aryloxyalkanoate dioxygenase, a cropwhich becomes resistant to a phenoxy acid-type herbicide such as 2,4-D,MCPA, dichlorprop or mecoprop, and an aryloxyphenoxypropionic acid-typeherbicide such as quizalofop, haloxyfop, fluazifop, diclofop,fenoxaprop, metamifop, cyhalofop and clodinafop can be produced (Wrightet al. 2010: Proceedings of National Academy of Science. 107 (47):20240-20245).

The crop includes, for example, a crop which has become possible tosynthesize a selective toxin known in Bacillus genus, using a geneticengineering technique.

EXAMPLES

Hereinbelow, the present invention will be described by way of Examples,but the present invention is not limited to these Examples.

First, evaluation criteria for an insecticidal effect, a herbicidaleffect, and phytotoxicity on crops described in the following examplesare shown.

[Plant Pathogen Controlling Effect]

The evaluation of the plant pathogen controlling effect is classifiedinto 0 to 100, in which the numeral “0” indicates no or little diseasesymptom by plant pathogen as comparison with the untreated crops at thetime of the investigation, and the numeral “100” indicates that thedisease symptom by plant pathogen is not completely or hardly observed.

[Herbicidal Effect and Phytotoxicity on Crops]

The evaluation of the herbicidal effect is classified into 0 to 100, inwhich the numeral “0” indicates no or little difference in the state ofpre-emergence or growth of test weeds as comparison with the untreatedweeds at the time of the investigation, and the numeral “100” indicatesthe complete death of the test plants or the complete inhibition oftheir pre-emergence or growth.

The evaluation of phytotoxicity on crops is shown by “no harm” when noor little phytotoxicity is found, “low” when a slight degree ofphytotoxicity is found, “moderate” when a medium degree of phytotoxicityis found, or “high” when a severe degree of phytotoxicity is found.
